Which logarithmic equation is equivalent to 82 = 64?

34kurt

Answer: Choice B

$2 = \log_{8}(64)$

======================================================

Explanation:

The original equation is $8^2 = 64$ with 8 as the base. That is also the base of the log when we get the final answer shown above. Logs are useful to isolate the exponent.

The general rule is that $\text{y} = b^{\text{x}}$ is equivalent to the log form of $\text{x} = \log_{b}(\text{y})$ where b is the base of each.

Given that (–2, y) and (4, 6) are points on a line whose slope is-4/3 , find y.

bulgar [2K]

Answer:

The value of y is 14

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have the points

$(-2, y)\ and\ (4, 6)$

$m=-\frac{4}{3}$

substitute in the formula the given values

$-\frac{4}{3}=\frac{6-y}{4+2}$

solve for y

$-\frac{4}{3}=\frac{6-y}{6}$

Multiply by 6 both sides

$-8=6-y$

$y=6+8=14$
